Hi and welcome to Fluther. You don’t have to go to a class to exercise. You can do it at home. You can start by walking and increase your speed and distance weekly. You can get aerobic DVD’s and do them at home. You can do sit ups, push-ups, leg lifts, etc., all at home. You need to just get up and move. Perhaps getting into an exercise regime, even if it’s just walking, will help with your depression. I don’t know if you see a doctor for that, but if not, maybe you should. Good luck!
